The device is capable of receiving, buffering, and translating a clock or data signal that is as small as 75 mV operating up to 3.5 GHz or 5.0 Gb/s, respectively. As such, it is ideal for SONET, GigE, Fiber Channel and backplane applications (see Table 6 and Figures 20, 21 22, and 23). Differential inputs incorporate internal 50 W termination resistors and accept LVPECL (Positive ECL), LVTTL/LVCMOS, CML, HSTL or LVDS. The differential 16 mA CML output provides matching internal 50 W termination, and 400 mV output swing when externally receiver terminated, 50 W to VCC (see Figure 19). These features provide transmission line termination on chip, at the receiver and driver end, eliminating any use of additional external components. The VBB, an internally generated voltage supply, is available to this device only. For single-ended input configuration, the unused complementary differential input is connected to VBB as a switching reference voltage. The VBB reference output can be used also to re-bias capacitor coupled differential or single-ended output signals. For the capacitor coupled input signals, VBB should be connected to the VTD pin and bypassed to ground with a 0.01 mF capacitor. When not used VBB should be left open. This device is housed in a 3x3 mm 16 pin QFN package. Application notes, models, and support documentation are available at www.onsemi.com.
